If open reduction for the treatment of a missed Monteggia fracture is performed when the patient is less than twelve years of age or within three years after the injury, good long-term clinical and radiographic outcomes can be expected.

The clinical features and results of treatment were reviewed in 17 traumatic palsies of the posterior interosseous nerve. Variations in clinical features depended on whether the recurrent branch or descending branch of the posterior interosseous nerve was injured. Seven patients had nerve repair, and two were treated by tendon transfers. Eight patients were treated conservatively. Sixteen of 17 patients recovered to more than M4 motor power at final follow-up. Associated muscle damage worsened the functional result.

Eighteen acute grade III collateral ligament injuries were treated by using the Mitek bone suture anchor. Seven were thumb metacarpophalangeal joint injuries, and eleven were finger proximal interphalangeal joint injuries. Seventeen patients were followed more than 12 months after surgery. All patients were able to use the digits in daily living activities within 5 weeks after surgery, and return to their original work or sports activities within 12 weeks. Pain was completely relieved in 15 patients. Loss of joint motion averaged 7 degrees. In all joints the postoperative lateral stress angle was within 10 degrees of that of the contralateral digit.

Complete removal of arteriovenous malformations of the hand, without functional impairment of the hand and fingers, is extremely difficult. A dorsalis pedis flap was used to reconstruct a soft-tissue defect, following complete removal of a malformation in the hypothenar region. This method allowed sufficient excision to militate against postoperative recurrence of the abnormality, while maintaining finger function. Two years after the operation, there has been no recurrence of the malformation and nearly normal finger function.
